Yellow fluid tends to be bile, which is from the upper small intestine and means your dog was throwing up on an empty stomach. This was probably from stress, or possibly from motion sickness - I would expect it to recur during car rides unless you train your dog to tolerate it better or have your veterinarian suggest some anti-nausea medication for the motion sickness.
Do you mean the yellow fluid? If it is yellow and it comes from your ear it is called earwax.
Then it is meconium stained.
The yellow fluid is most likely stomach acid and is probably a result from throwing up on an empty stomach.
It means you have a really disgusting knee.
If "normal" fluid intake is assumed to mean a properly hydrated person, urine should be clear to slightly pale yellow; the less colour, the better.
